Alert From the Experts

The emerald ash borer (Agrilus planipennis) has been confirmed in Colorado. This invasive Asian beetle has decimated ash trees in the Midwest since its discovery in 2002, costing millions of dollars to homeowners and cities. Early detection is key to controlling the emerald ash borer! Look for signs of infestation and report them to your county extension office.

Denver Parks & Recreation has started a campaign called “Be A Smart Ash.” Spend some time on their website and learn how you can help protect your ash and our urban canopy by identifying, treating and replacing Denver’s ash trees.
